Jude (jûde), Epistle of. It is referred to by Clement of Alexandria, Tertullian, and Origen. It was probably written in Palestine, about a.d. 65. This epistle seems to have been intended to guard the faithful against prevalent errors, and to urge them to constancy in the faith. It is not improbable that Peter had read Jude's epistle, when he wrote his Second epistle; and that the thoughts, under the influence of the Holy Spirit, had made a strong impression upon his mind.
